Original GitHub issue: https://github.com/sigma67/ytmusicapi/issues/179

Albums and tracks work just fine with get_watch_playlist, but playlists don't (if I'm not doing something wrong).

Ther error is:

KeyError: 'content'

At:
  /usr/local/lib/python3.9/dist-packages/ytmusicapi/parsers/utils.py(210): nav
  /usr/local/lib/python3.9/dist-packages/ytmusicapi/mixins/watch.py(78): get_watch_playlist

A simple test case:

import ytmusicapi
yt = ytmusicapi.YTMusic()
yt.get_watch_playlist("VLPLMOhiB5NIEx7us1pGnMZXGcN6dSL45uZu")

You need to call it like this

yt.get_watch_playlist(playlistId="PLMOhiB5NIEx7us1pGnMZXGcN6dSL45uZu")

Sorry, I messed up the test case. The error still occurs with

yt.get_watch_playlist(playlistId="VLPLMOhiB5NIEx7us1pGnMZXGcN6dSL45uZu")

too

I must have messed up the playlist id too, thank you for the help.

Just in case someone finds this useful: I don't really understand why, but it is always necessary to remove the "VL" from the beginning of the playlist IDs.

Yes, that's why I removed the VL in my comment above.

YouTube sometimes uses the VL prefix internally. I think it's mainly a prefix to differentiate actual playlists from radio playlists and others. Some other endpoints like get_playlist can already handle the VL prefix, I suppose we could add something to `get_watch_playlist_ as well.
